Fabrication and characterization of multifunctional composites

“This study details the research to facilitate fabrication and characterization of novel structural composites reinforced with carbon fibers. Across industries, materials with high performance-to-weight ratio are sought after. Using carbon fibers as secondary phases in these proposed composites, specific characteristics can be tailored in these materials to manufacture strong, lightweight, high performance structures. The first part of the research focused on the improvement in the mechanical properties of the composites using carbon fiber reinforcement. As a part of this study, toughened ceramic composites with predictable failure patterns were produced using carbon fiber inclusions. A closed-form analytical model was developed to enable expedited analyses of various composite designs. A high-speed additive manufacturing process to fabricate high-strength, lightweight structural components using short, long and continuous carbon fiber reinforcement was also established. Therefore, enabling component-level improvement by delivering customizable structures with high strength-to-weight performance at a low cost. The second part of the research expanded this further to a system wide performance-to-weight improvement through the fabrication and characterization of multifunctional composites. As a part of this research multifunctional structural energy composites were additively manufactured with active-conductive material doped polymer matrix cathode and conductive carbon fiber reinforcement as anode. A systematic study conducting mechanical, electrochemical and microstructural analyses helped in establishing the feasibility of the developed composites to facilitate system-level improvements, making them attractive for widespread multifunctional structural applications”--Abstract, page iv.
